The difference is that constant speed doesn't change but variable speed does. (change)
Velocity is speed with direction
The technical difference is that speed has no direction but velocity has one.
The difference between an object's speed and an object's velocity is that the object's speed is how fast it is going, and the object's velocity is how many units of speed the object has traveled.
Instantaneous speed is speed measured at a specific time. Speed is an average.

Draw several circles from the under ground point called focus.Color it by red and blue alternatively.One is for primary and the next one is for secondary.The gap at focus between primary and secondary should be very close and as the distance goes beyond focus the gap between primary and secondary should be more.This difference represents the speed difference of those two waves.
ram is primary storage
secondary index is a key which is created other than primary key, to speed up processing.
1)Synchronous motors are those that run only at Synchronous speed i.e. constant speed. But Motor can run in various speeds. 2)Synchronous motors runs at same speed of magnetic filed. but if one consider case of induction motor the rotor rotates at different speed than revolving magnetic field. there is slip between field and rotor.

difference between 3 and four speed is, a 3 speed has 3 forward gears. a 4 speed has 4 forward gears
It's the 3rd iteration of the iPhone. The primary difference between it and its predecessor the iPhone 3G is that the 3GS is faster and can record video. The S stands for speed.
